FRANKFURT MAIN: Audi chief executive Rupert Stadler was arrested on Monday in connection with parent company Volkswagen’s “dieselgate” emissions cheating scandal, with prosecutors saying they feared he might try to suppress evidence.
The dramatic development comes a week after Munich prosecutors raided Stadler’s home after charging him with fraud and falsifying documents that allowed diesel vehicles equipped with cheating software to be sold to European customers.
Four police officers detained the Audi boss at his home at between 6 and 7 am, a spokesman for Munich prosecutors told AFP, saying that the arrest was justified as he is suspected of “seeking to influence witnesses or other suspects”.
Stadler has denied the accusations and has said he is ready to be interrogated from Wednesday, added the spokesman.
Hours after the arrest, the VW group’s management named Dutchman Bram Schot, who joined VW in 2011, to take over from Stadler as interim CEO.
Stadler is the most senior executive yet to be detained in the dieselgate crisis, which started when the Volkswagen group admitted in 2015 to installing so-called “defeat devices” in some 11 million diesels worldwide that made them seem less polluting in lab tests than they actually were on the road.
The affected vehicles involved VW’s own-brand cars, but also those made by Audi, Porsche, Skoda and Seat.
VW’s luxury subsidiary Audi has long faced suspicions that its engineers helped create the software used in the scam.
Audi’s former head of engine development, Wolfgang Hatz, was taken into custody in Germany in September 2017 and remains behind bars.
A manager at Porsche was also detained in April. He was identified by German media as Joerg Kerner, an engineer in charge of Porsche’s engine division who was working at Audi when the diesel scandal broke.
And German authorities earlier this month ordered the recall of some 60,000 Audi A6 and A7 cars across Europe to remove illegal emissions control software — using a different technique however than the one at the heart of dieselgate.
“Audi needs a new start,” said auto industry expert Ferdinand Dudenhoeffer of the CAR research centre.
Stadler, 55, who joined Audi in 1990 and has been its CEO since 2007, has enjoyed the full backing of VW’s top brass so far.
But Dudenhoeffer said that may change, given the “very serious” allegations against him.
Stadler’s arrest is the latest blow to the Volkswagen group, which has struggled to shake off the dieselgate crisis and continues to face a litany of investigations at home and abroad.
Two former VW chief executives — Martin Winterkorn and his successor Matthias Mueller — have both landed in the sights of German prosecutors.
They are suspected of knowing earlier than they have admitted about the cheating, meaning they may have failed in their duty to inform investors in the car giant about the financial risks.
US prosecutors also indicted Winterkorn last month, saying he knew of the company’s emissions cheating as early as May 2014 but decided to continue.
Current boss Herbert Diess has also been accused of knowing about the scam before it became public — an allegation rejected by the firm last month.
The diesel scandal has so far cost the VW group more than 25 billion euros ($29bn) in buybacks, fines and compensation, mainly in the United States where the cheating scam was first uncovered.
But pressure has been mounting on the auto giant to make amends in Europe too.
Just last week, VW agreed to pay a one-billion-euro fine to settle a probe by German prosecutors.
In doing so, VW said it admitted its “responsibility for the diesel crisis”.
Despite the controversy, the VW group last year reported global sales of 10.7 million vehicles — a new record.
But the saga has cast a wider pall over Germany’s vaunted car industry, with suspicions of emissions manipulation spreading to rivals BMW and Mercedes-owned Daimler.
To date, just two people have been convicted over “dieselgate”, both in the US.
Former VW executive Oliver Schmidt is serving a seven-year sentence after pleading guilty to conspiracy to commit fraud and violating the US Clean Air Act.
VW engineer James Liang, who cooperated with investigators, was handed 40 months in jail last year.
